Problems solved by technology

[0003] As people's living styles become more and more diverse, doors and windows are gradually occupying and expanding their market. At present, more door and window materials on the market are mainly aluminum alloy, color steel, and PVC materials, and aluminum alloy is because of its higher hardness, Light weight, no aging, beautiful and practical after color coating, so it is favored by the market, and the market demand is more and more strong, but the processing hardness of traditional aluminum alloy is too high, the plasticity is poor, the processing difficulty is relatively large, and the product price is obviously higher than similar products Common aluminum alloy plate products, thus affecting its popularization and use
